Abstract
Disclosed is an automobile equipped with an engine having an electronically-controlled throttle valve adapted to have an opening angle which is controlled according to an accelerator-pedal depression amount. The engine further includes an accelerator pedal sensor, an actuator adapted to selectively open and close the throttle valve, and a controller. The controller is adapted to calculate a target throttle opening angle corresponding to the accelerator-pedal depression amount, and output a continuous control signal corresponding to the target throttle opening angle, to the actuator. The controller is operable, in a traveling environment of the automobile or an operating condition of the engine where a required engine power is less than an engine power corresponding to the target throttle opening angle, to convert the continuous control signal into a pulsed control signal, and output the pulsed control signal to the actuator.
